ObjectiveTo analyze the factors influencing the total number of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer.MethodsThe clinicopathologic data of patients who underwent laparoscopic D2 radical resection of gastric cancer in this hospital for advanced gastric cancer from January 2018 to July 2020 were retrospectively analyzed. The statistical analysis was conducted to analyze the influence factors (age, gender, tumor size, tumor site, body mass index, infiltration depth, lymph node metastasis, HER-2 gene amplification status, presence or absence of vascular tumor thrombus, presence or absence of nerve infiltration, differentiation type, pTNM, Borrmann type, and type of gastrectomy) on the number of harvested lymph nodes.ResultsA total of 536 patients met the inclusion and exclusion criteria were included. The results of univariate analysis showed that the total number of harvested lymph nodes during laparoscopic radical gastrectomy for advanced gastric cancer was correlated with age, tumor size, tumor infiltration depth, lymph node metastasis, pTNM stage, Borrmann type, and type of gastrectomy. That was, the younger the patient was (≤ 54 years old), the larger the tumor was (long diameter >3.5 cm), the later the Borrmann classification was (type Ⅲ, Ⅳ), the deeper the tumor invasion was, the more the number of lymph node metastasis was, the later the pTNM stage was, and the more the number of lymph nodes was detected in patients undergoing total gastrectomy (all P<0.05). The multiple linear regression analysis showed that the age, lymph node metastasis, and PTNM stage had significant effects on the number of harvested lymph nodes. The multiple linear regression model was statistically significant (F=6.754, P<0.001). 11.2% of the variation in the number of harvested lymph nodes could be explained by the age, lymph node metastasis, and pTNM stage (adjusted R2=11.2%). ConclusionsNumber of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer is greatly affected by the age of patients, lymph node metastasis, and pTNM stage. So patients should be evaluated objectively and individually according to their age so as to harvest sufficient number of lymph nodes, which is conducive to accurately judge pTNM stage, formulate accurate adjuvant treatment scheme, and improve prognosis of patients.
Objective To investigate the technique and feasibility of hepatic pedicle vascular control in laparoscopic hepatectomy. Methods From May 2005 to June 2011, 95 cases of hepatectomies were performed by laparoscopy in the Department of Minimally Invasive Surgery, The First Affiliated Hospital, Guangxi Medical University.The characteristics of these cases were analyzed.

ObjectiveTo emphasize the important role of video-assisted thoracoscopic surgery (VATS) in treatment of mediastinal bronchogenic cysts (MBCs).MethodsWe retrospectively reviewed the clinical data of 112 patients (53 males and 59 females) of mediastinal bronchogenic cysts who underwent VATS in our institution between April 2001 and Aprial 2016. Median age was 4–75 (45.6±15.0) years. All patients underwent chest CT preoperatively. The patients were divided into two groups: an anterior mediastinum group, 47 patients; a middle and posterior mediastinum group, 65 patients including 35 patients in the middle mediastinum, 30 patients in the posterior mediastinum. The average diameter was 0.5–22.0 (3.50±2.33) cm. The average CT attenuation was 0–67 (35.5±15.3) Hu on unenhanced CT. We began each operation with the VATS technique.ResultsThe CT diagnostic accuracy for group middle and posterior mediastinum with CT value≤20 Hu was higher than others (61.5% vs. 13.1%, χ2=17.675, P<0.001). A total of 111 patients underwent VATS, only one patient converted to open thoracotomy. Cyst resection and thymectomy were conducted in 45 patients, cyst resection and extended thymectomy were conducted in 2 patients in the anterior mediastinum group. Simply cyst resection were performed in the middle and posterior mediastinum group (n=65). The average operative time was 40–360 (104.5±43.1) min. The average intraoperative blood loss was 5–600 (57.9±88.9) mL. The intraoperative complication rate was 3.6% and the incomplete resection rate was 6.3%. The main reason for these was severe adhesion between the cyst and mediastinal structure. No serious postoperative complication was found. Follow-up was done in 99 patients, and the mean follow-up time was 42 (12–191) months. There was no local recurrence.ConclusionVATS resection of MBCs is a safe and efficacious procedure, and minimally invasive and surgical resection should be performed as early as possible for MBCs.
Objective To compare the digital drainage system and the traditional drainage system in the patients after lung surgery, and to evaluate the advantages of digital drainage system. Methods A retrospective analysis of consecutive 42 patients with lung surgery between September 2016 and May 2017 in Beijing University International Hospital was done. There were 30 males and 12 females with a median age of 34 years ranging 19-81 years. After the surgery 21 patients adopted Thopaz digital drainage device (a DDS group), and the other 21 patients adopted traditional drainage (a TDS group). Duration of air leakage and chest tube placement, length of hospital stay, thoracic drainage volume within 48 h and hospitalization expenses in the two groups were compared. Results The patients in the two groups were all successfully discharged. Compared with the TDS group, duration of air leakage and chest tube placement and length of hospital stay significantly shortened in the DDS group (35.6±16.3 h vs. 48.2±20.1 h, P=0.02; 50.0±16.1 h vs. 62.0±20.4 h, P=0.03; 5.9±2.3 d vs. 7.8±3.5 d, P=0.02), and thoracic drainage volume within 48 h and hospitalization expenses showed no significant statistical difference between the two groups. Conclusion Using digital drainage system after lung surgery can significantly shorten the duration of air leakage and the postoperative drainage, at the same time, without increasing the overall hospitalization expenses.
Objective To evaluate the clinical experience and skills of laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection in order to spread and popularize this kind of operation. Methods Under general anesthesia, 32 patients (42 sides) with inguinal hernias were repaired by laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a dissection balloon from August 2005 to December 2007. Results All of operations were successfully performed. The operative time was 60-120 minutes, the blood loss was 20-60 ml, and the length of postoperative hospitalization was 3 days. All cases were followed up for 8 to 18 months and found no recurrence. Conclusion Laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection is feasible, reliable and effective, offering a low recurrence rate, while its price is higher than tension-free herniorrhaphy by traditional method.
Abstract： Objective To evaluate the safety, feasibility, and clinical outcome of complete video-assisted thoracoscopic surgery （VATS） lobectomy for patients with early-stage non-small cell lung cancer （NSCLC）. Methods We retrospectively analyzed the clinical data of 160 consecutive patients（the VATS group, 83 males and 77 females with average age at 60.8 years）with early-stage NSCLC who underwent complete VATS lobectomy between January 2005 andDecember 2008 in Zhongshan Hospital of Fudan University，and compared them with 357 patients（the thoracotomy group, 222 males and 135 females with average age at 59.5 years）who underwent open thoracotomy in the same period. Results The conversion rate of the VATS group was 5.0%（8/160）. The operation time of the VATS group was significantly shorter than that of the thoracotomy group（113.0 min vs.125.0 min, P=0.039）. Length of postoperative hospital stay was not statistically different between the two groups（10.3±4.3 d vs.9.1±4.6 d，P=0.425）. The postoperative morbidity of the VATS lobectomy group and the thoracotomy group was 9.4%（15/160）and 10.1% （36/357） respectively，and the postoperative mortality of the two groups was 0.6%（1/160）and 2.0%（7/357）respectively. There was no statistical difference in the mean group of lymph node dissection （2.4±1.5 groups vs.2.4±1.7 groups，P=0.743） and the mean number of lymph node dissection （9.8±6.3 vs.10.1±6.4，P=0.626） between the two groups. The overall 5-year survival rate of the VATS group was significantly higher than that of the thoracotomy group （81.5% vs.67.8%, P=0.001）. Subgroup analysis showed that the 5-year survival rate of pⅠa stage, pⅠb stage, and pⅢa stage was 86.0%, 84.5%, and 58.8% respectively in the VATS group, and 92.9%, 76.4%, and 25.3% respectively in the thoracotomy group. Conclusion Complete VATS lobectomy is technically safe and feasible for patients with early-stage NSCLC. The lymph node dissection extension of complete VATS lobectomy is similar to that of open thoracotomy, and long-term outcome of complete VATS lobectomy is superior to that of open thoracotomy. Randomized controlled trials of large sample size are further needed to demonstrate superiority.
